ADJUSTABLE MOLD-JACKET.

Application filed October 4, 1917.

- of which the following is a specification.

The device forming the subject matter of this application is anadjustable mold jacket, and one object of the invention to provide novelmeans for connecting 'the walls or plates of the jacket, adjustably atthe corners, to permit a variation in the size of the jacket.

Another object of the invention is to provide novel means whereby thewalls of the jacket, at the will of an operator, may be tilted withrespect to each other, so that the jacket has a tapered form.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

\Vith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

- In the drawings Figure 1 shows in side elevation, a jacket constructedin accordance with the present invention Fig. 2 is a top plan of thejacket;

Fig. 3 is a perspective view showing one of the constituent plates ofthe jacket;

Fig. 4 is a fragmental side elevation, showing the walls tilted to anintermediate position;

Fig. 5 is an elevation wherein the struc ture delineated in Fig. 4 isviewed at right angles to the showing of Fig. 4;

Fig. 6 is a plan showing a slight modification in the invention.

In carryin out the present invention there is provided, as an article ofmanufacture, a plate 1 having an extension 2 at one end, in which thereis formed an opening 3. In the plate 1 near to the extension 2, spacedslots 4 and 5 are formed, there being an intermediate slot 6 in theplate,

between the spaced slots 4 and 5. As indicated at 7, the opening 3 maybe duplicated, and as indicated at 8, the slots 4, 5 and 6 may beduplicated, to permit an adjustment in the size of the jacket of whichthe plate 1 constitutes a part. The plate 1 is provided near that endwhich is remote from the slots 4, 5 and 6, with an outstanding lug 9having an opening 10 in which is slidably mounted a rod or bolt 11,provided at its outer end with a head 12, and carrying at its inner endan adjusting device such as a nut 14. A compression spring 15 surroundsthe bolt 11, one end of the compression spring abutting against the nut14, and the other end of the compression spring abutting against the lug9. That end of the plate 1 which is adjacent the lug 9 is supplied withspaced tongues 16 and 17 and with an intermediate tongue 18. The tongues17, 18 and 16 on one plate, are adapted to be received loosely, in theopenings 4, 6 and 5 of an adjoining plate to form a corner joint. endedge of the plate 1 adjacent the tongue 16 is disposed, as shown at 19,at right angles to the longitudinal edge 20 of the plate 1. Theremaining portion 21 of the said end edge of the plate is disposed at anacute angle to the longitudinal edge 20.

The inner edge 22 of the slot 5 is at right angles to the edge 20. Theouter edge 23 of the slot 5 is disposed at an acute angle to the edge20. The slot 5, therefore, tapers toward the longitudinal center of theplate 1. One part 24 of the inner edge of the slot 6 is disposed atright angles to the edge 20. The other part 25 of the inner edge of theslot 6 is disposed at an acute angle to the edge 20. One part 26 of theouter edge of the slot 6 is at right angles to the edge 20. The otherpart 27 of the outer edge of the slot 6 is disposed at an acute angle tothe edge 20. The inner edge 28 of the slot 4 is inclined with respect tothe edge 20, the outer edge 29 of the slot 4 being disposed at rightangles to the edge 20. The slot 4, therefore, tapers inwardly toward thelongitudinal center of the plate 1, and it may properly be stated thatthe slots 4 and 5 taper toward each other.

In practical operation, the tongues 16, 18 and 17 on the end of oneplate are received, respectively, in the slots 5, 6 and 4 of anadjoining plate. The bolt 11 on one plate passes through the hole 3 inthe adjoining plate, and the head 12 engages the outer face of saidadjoining plate. By adjusting the nut 14, the 'efi'o'rt of the spring 15may be varied, and the plates may bev he1d-toedge ofthe tongue 17 bearsagainst the edge 290i the slot 1-, a part ofthe outer edge of the tongue1S'bears against the portion 26 of the slot 6', a portion of. theinner'edge of the tongue 18'bearing against the part 24 or. the slot 6;and the inner edge of the tongue 16bearing against the edge '22 of theslot 5.

Let it be supposed that it is desired to give a taper to the jacket.Then the inner surface of one platel bears against the portion 21 oftheend edge of an adjoining plate. Theinner edge of the tongue 17'cooperates with the inclined" edge 28 of the slot 4, a portion of theinner edge ofthe tongue 18 coe'perating with the part 25' of the slot'6, a portion of the outer edge of the tongue 18 coacting with the part27 of the slot 6, and the outer edge of the tongue 16' c'oacting withthe edge 23 of the slot 5.

Suppose that it is desired to give a taper to the acket, but, at thesame time, to have a less pronounced taper than the one resulting fromthe operation above mentioned. Then the constituent adjoining plates ofthe jacket are disposed as shown in Figs. 4: and 5-, the inner surfaceof'one plate resting on the angle defined by the portions 19 and 21of'the endedge of an adjoining. plate, as indicated in Fig. 1'. Una-ersuch circumstances, the inner and outer edges of the tongue 17 arespaced from the walls 28 and '29 of the slot 4,.as shown in Fig. 5, theinner and outer edges of the tongue 16 being spacedfrom the edges 22 and23- of the slot 5, as shown in Fig. 5. The outer edge of the tongue 18has a bearing on the angle defined by the edges 26 and 27 of the slot 6and the inner edge of the tongue 18 has a bearing on: the angle definedby theparts 25 and :24 of the said slot '6. v

When it iswdesired to' change the dimensions of the-mold, the tonguesmay be shifted? from the openings 5,. 6 and 4t, tothe openilngsdesignated by the reference character 8 in'Fig. 3.

It will be observed that the device formco ies ofthfs patent may beobtained. for

Having thus described the invention, what is claimed is? '1. A device ofthe class described comprisingan'gular walls, one of which ispro vid'ejdwith spaced slots and with an interinediate slot between thesp'acectslots, the other of which is provided with spaced tonguesloosely received in the spaced slots,
